There is possibly a new ninth planet. And no, we’re not talking about bringing back Pluto, which was demoted to dwarf planet status in 2008.
Astronomers at Caltech have detailed evidence for the existence of a new ninth planet, beyond the orbit of Pluto. Professors Michael E. Brown and Konstantin Batygin noticed disturbances in the orbits of six objects in the Kuiper belt. The alignment of these orbits leads the researchers to believe that they are being influenced by a ninth planet, which orbits the sun so far away that it would take 15,000 years to orbit the Sun. Scientists predict that this new planet, which they are calling Planet X or Planet Nine, has a mass 10 times larger than Earth.
